Hi, I m 18 and have been using levlen for the past six months. My boyfriend (of 4 years) and i made love for the first time on the 25th of December 2012. I had been taking my pills every day at aprox the same time (only 1-3 hours late on some occasions). I have just finished my last active pill yesterday (28th Dec) and should get my period on Monday (31st Dec). I know that the chances are low but I have had terrible anxiety about getting pregnant. How likely do you think it is? Thanks
